How to Plant
STEP 1) First, decide on a planting location. Consider carefully what kind of sun, soil, and growing-space your tree or shrub will need.
STEP 2) Once you've located the perfect spot, the hole you are digging must be at least double the width and as deep as the root system you are planting.
STEP 3) Remove the plant from the pot and place the root ball in the hole. The top of the root system should be level with the ground. Before placing the tree or shrub in the hole, use your hands to gently break up the root system.
STEP 4) Once the plant is in place, backfill the hole with native soil and any leftover potting material.
STEP 5) Pack down the soil to eliminate any air pockets.
STEP 6) When finished, water thoroughly.
Care Guide

To encourage a vigorous and high yielding plum tree, thin the tree's fruit in May and again in July, removing the damaged and diseased fruit so that the rest have room to grow. Prune plum trees in the winter. Regularly remove suckers from around the base of the tree.
